$ Generate cURL commands
Set your URL, method, headers, body, and auth options and get a ready-to-run cURL command for Linux or PowerShell.
Request builder
Fill in your request parameters and get a ready-to-run cURL command.
Linux / macOS
Standard curl command — works on Linux, macOS, and Windows (with curl.exe).
curl \ 'https://api.example.com/users'
PowerShell
Invoke-WebRequest — native PowerShell cmdlet (Windows PowerShell 5.1+ / PS 7+).
Invoke-WebRequest ` -Method GET ` -Uri "https://api.example.com/users"
Why this tool exists
Vultio cURL Generator is for the opposite starting point from the converter: instead of pasting an existing command, you know the request you want to make and need the exact shell command assembled correctly.
That matters more than it sounds. Many developers remember the broad idea of curl syntax but still lose time checking how to quote JSON bodies, attach bearer tokens, add URL-encoded form content, or produce a Windows-friendly PowerShell equivalent.
This page turns the repetitive mechanical part into a form workflow. You define method, URL, headers, authentication, body type, and options once, then copy a clean Linux/macOS curl command or a PowerShell Invoke-WebRequest version for documentation, testing, support handoff, or automation.
It is particularly useful when you want a canonical request example that other people can run without guessing what your local environment, shell history, or browser session was doing behind the scenes.
Common use cases
Example input / output
POST with Bearer token
GET with API Key header
PowerShell request for a self-signed dev server
Common errors
cause:curl is not installed on the machine, or the active shell does not have it on PATH.
fix:Install curl via your package manager on Linux/macOS, or use the built-in curl.exe available on modern Windows versions.
cause:The target environment uses a self-signed or untrusted certificate, which is common in development or internal staging systems.
fix:Enable the skip-SSL option only for development testing. Do not normalize that flag in production examples unless you explicitly explain the risk.
cause:The transport syntax may be correct while the business-level request is still wrong, often because of an incorrect Content-Type, missing auth scope, malformed body, or mismatched header name.
fix:Verify the exact body format the API expects, review auth configuration, and compare the generated command with working examples from the service documentation.
cause:Quoting and escaping rules differ across bash, zsh, PowerShell, and copied documentation contexts, especially for JSON strings and embedded quotes.
fix:Use the Linux/macOS output in POSIX-style shells and the PowerShell output in Windows environments rather than mixing the two styles.
How developers use it in practice
When support or QA needs a reproducible request, generate a clean command with placeholders instead of pasting something copied from your local shell history. It is easier to share and safer to sanitize.
If you include a generated command in docs, add one line explaining what the request proves: auth flow, schema shape, webhook simulation, or endpoint health. That makes the command much more useful during handoff.
A clean cURL request is often the best intermediate format. Once the request is correct in curl, you can convert it into application code using the cURL Converter with less ambiguity.
When writing onboarding or support documentation, keep the generated command structurally complete but replace live tokens, emails, and internal IDs with clear placeholders that others can swap safely.
When not to use this tool
Limits and implementation notes
The generator is strongest for normal API traffic: methods, headers, bodies, auth, redirects, compression, and timeouts. Highly specialized multipart or streaming workflows may still need manual refinement.
Linux/macOS curl and PowerShell have different escaping rules. The tool generates both styles so you do not have to improvise, but environment-specific edits may still be necessary.
The command can be well-formed while the endpoint still rejects it because the schema, auth scope, or headers do not match what the server expects.
They are excellent for testing, docs, and handoff, but long-term integrations should still move into versioned scripts, typed clients, or automation pipelines with proper secret handling.

Frequently asked questions
What is a cURL generator online?
A cURL generator lets you fill in HTTP request parameters — URL, method, headers, body, authentication — using a form, and produces a ready-to-run curl command without needing to memorize flag syntax.
What is the difference between the Linux and PowerShell output?
The Linux/macOS output uses standard curl syntax with backslash line continuations. The PowerShell output uses Invoke-WebRequest, the native PowerShell cmdlet, with backtick continuations and @{} header hashtables.
How do I use the generated command in PowerShell?
Copy the Invoke-WebRequest command and paste it directly into a PowerShell terminal (Windows PowerShell 5.1+ or PowerShell 7+). No extra tools needed — Invoke-WebRequest is built into PowerShell.
Can I add custom headers?
Yes. Use the Headers section to add any number of key-value header pairs. Common headers like Content-Type and Authorization are also set automatically when you choose a body type or auth method.
Is my data sent to a server?
No. The cURL command is generated entirely in your browser. None of your URL, credentials, or payload is transmitted anywhere.
